You’re usually advised to avoid drinking tap water while travelling in a foreign country, but is this really necessary? Here in the UK we have world class water sanitation and levels of toxins and bacteria are tightly controlled. While many other countries have equally excellent water safety standards, that sadly doesn’t apply everywhere in the world. Before you travel, visit the National Travel Health Network and Centre (NATHNAC) website to check advice on the country you’re travelling to.
In countries with poor levels of sanitation, don’t drink water straight from the tap. Diseases like travellers’ diarrhoea, hepatitis A, typhoid and cholera are carried in dirty water so only drink bottled or boiled water. If it isn’t possible to boil your water, using iodine or chlorine disinfectant tablets will purify water, though you may want to use them in combination to ensure all forms of parasites are killed.
Remember; don’t get caught out with things like ice in your drink or food that has been washed in tap water. Foods like water melon may be stored in water to make them more juicy so be vigilant. Though these measures seem a lot of hassle, they’re a small price to pay for your health.
